The Nintendo 64 was originally called the Ultra 64, as a tribute to several toys they manufactured in the late 1960's such as the Ultra Hand. However, Konami still held a trademark on the name "Ultra Games", and Nintendo was forced to change the name and logo for their new console.

Nintendo removed the Nintendo 64's ability to use RGB output (SCART/Component), but earlier versions of the console still have the ability to do so. An RGB signal can be achieved on the N64 by simply jumping a few wires on the motherboard and adding a few more electronic components.

64DD is a disc drive add-on for the Nintendo 64 that was announced on the Shoshinkai game show (Space world today) in Japan, talked about by Shigeru Miyamoto and released in Japan in 1999. It was never available outside of Japan.
